Concealed door hinge and stop



Dec. 10, 1929.- J. A; HOEGGER CONCEALED DOOR HINGE AND STOP Filed April5. 1928 Patented Dec. 10, 1929 Quarr- CONCEALED DOOR HINGE AND STOPApplication filed April 3,

My invention relates to improvements in door hinges and stops, and theobject of my invention is to produce a very cheap, simple and strongstructure which enables the door to be swung in such a way that thehinges arefconcealed, the door will lie flat when closed against thearticle with which it is connected, and the stop will be arranged so asto positively and easily limit the opening movement of the door. Thefeature of the link stop sucha's I show is not broadly new, but thepractical way in which it is applied is believed to be novel.

Another object of the invention is to pro duce a structure of this kindwhich enables the door hinge and stop to be easily removed when for anyreason it is necessary, without disturbing the structure to which thedoor is applied. In the accompanying drawings I have shown the doorapplied to a wall cabinet, a use to which it is particularly applicable,but the invention is in nowise limitec to such use. I

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar reference characters indicatecorresponding parts in all the views.

Figure 1 is a broken plan view of the improved structure. I

Figure 2 is a vertical section on the line 2-2 of Figure 4.

Figure 3 is a section on the line 33 of Figure 1.

Figure 4 is a section on the line 4. 4 of Figure 1, and

Figure 5 is a detail perspective view of a brace used at the corner ofthe door which is hinged.

In the drawings I have shown the upper corner of a door and itsconnections, but it will be understood that the lower corner isidentical and so it is needless to show both, as the door is hinged atthe upper and lower corners.

Without limiting it to this use, I have shown the door applied to acabinet 10 which is mounted in a recess in the wall 11, and has a borderflange 12 lying against the wall around the opening therein. To theupper 50 and lower parts of the flange at one side of 1928. Serial No.266,884.

the cabinet corresponding to thevupper and 3 lower corners therof, areattached blocks 13 to support the, door. These are rigidly secured, andI have shown the upper one fastened by screws 14. Its outer end isrounded as shown at 15 to permit the door to swing easily. Y I

The door 16 can be of anyv usual orpreferredtype or style, and isadapted to close the opening of the cabinet 10 and lie flat against thewall. border frame 17 preferably of channel iron, and at the upper andlower hinge corners in can be reinforced as at 18 in Figure 1 to giveadditional strength. The inner corner portions' of the door'arepreferably rounded slightly as at 19 (see Figure 1) to facilitate easyopening and closing.

. The door is hinged on the screw studs 20 which extend through apartoft-he frame 17 (see Figures 2 and 4) the body of the stud extremitybeing screw threaded and extend-' ing into a tap 20 in thefangle brace21. v I

will describe'this brace as applied to the upper corner of the door, andit will be understood that the same arrangement willobtain at the lowercorner; I

. '1 The brace 21 has a vertical arm 22 extending along one edge of thedoor within'the "frame 17, and a horizontal and longer arm 23 extendingalong the door top within the top of the frame 17 It will beunderstoodlthat the edge of the door will be recessed to receive thisbrace. The brace is fastened to the door 7 It is provided with a servingas a pivot for'the door and the lower Lengthwise of the arm 23 is a way26, the wall of which is cut awayat the top as at27, and atone end ithas a shoulder 28, and at the opposite end the arm is slightly reducedas at 29 to permit-the abutment 30 ofthe limiting link 31 to be insertedin the way easily when the structure is assembled.

The link 31 limitsthe opening movement of the door. The inner end of thelink is at tachedby a screw 32 to the reduced part 33 t1on very strong.

of the block 13. It will be seen, therefore, that when the door closes,the abutment 30 will slide along the way 26 and permit the door to closesnugly over its opening, and when it is opened the abutment 30 willstrike the shoulder 28 and limit the opening movement. c

It will be noticed'that the structure which I have described isverystrong andsimple, and that it dispensesnvith ahinge prope1;,.as thestuds serve this-purpose and the blocks 13 and angle braces n'ialre thecornerconn'ec- A particular advantage, also, is that by removin'gthescrewsQO and 32 at the top of the door, and the corresponding ones atthe bottom, as the structurehere willb'e'identical,the door canbe-readily taken off whenever it is "necessarywithout "disturbingthejpartto whiclrit*ishttached. It will i also be noticedthat'the1b1oc'ksf13 can be pro- 'du'ced "and attac'h'edjin "anyconvenient Way, the essential thing being to have these blocks I or ledgesri'gid' on the par'tto which "they "are attached so as to makea'fi'rm: support forthe door. ltwill alsobe 'observedthat when the 'dooris shut thedoor closes over theblocks '13 c which'fit in thecorresponding part of the said elements, a limiting 'lin'l: pivoted tothe V I supportingelements and sliding inwaysrin :the door, anddetaohablei fastening elements, one setls'erving as flpintles for thedoor and extending through the'outerpartof the door into the supportingelements, and the other "serving to attach the links to the supportingelements. e
